Issue description

Hello Batocera Team,

the boot configuration from external usb/scard is broken for gtking/gtkingpro (and maybe other amlogic based platforms using uboot bootloader) :
boot exits and fallbacks to recovery.

Detailed reproduction steps

I tried the latest release for gtkingpro (batocera-s922x-gtkingpro-37-20230618.img.gz) and flashed it on sdcard. I booted it and failed, falling back to recovery.

Details of any attempts to fix this yourself

I found this resource related to this issue : forum providing a working configuration patch based on this work.

Details of any modifications you have made to Batocera.

I adapted the patch to make it work with Batocera 40 on gtkingpro platform using image batocera-s922x-gtking-40-20240802.img.gz for basis. And I got a bootable and fully functional (wifi, bluetooth, ...) installation for batocera 40 on gtkingpro.

Logs and data

I provide here the patched configuration to be applied on a flashed image on sdcard(/usb storage) of batocera-s922x-gtking-40-20240802.img.gz.
